OpenBSD Errata: June 14th, 2018 (libcrypto)

Errata patches for libcrypto have been released for OpenBSD 6.3 and 6.2.
DSA and ECDSA signature generation can potentially leak secret information
to a timing side-channel attack.
Binary updates for the amd64, i386, and arm64 platforms are available via
the syspatch utility. Source code patches can be found on the respective
errata pages:
https://www.openbsd.org/errata62.html
https://www.openbsd.org/errata63.html
For users running 6.3, the syspatches will be delayed approximately two days.
Use the source code patch if you need the fix before then.
